Vintage Note
Please note that this is a pre-owned vintage timepiece approximately 40+ years old. Minor scratches, patina, bracelet stretch, and signs of use are normal characteristics of vintage watches and add to their originality and charm. Original lume may have naturally aged over time and may no longer glow brightly. Water resistance is not guaranteed due to the age of vintage seals and gaskets.
